“…Interspecific crosses at multiple ploidy levels within the Vaccinium sections have been common and important for germplasm enhancement, especially in section Cyanococcus where crosses between V. darrowii (2n), V. corymbosum (4n), and V. ashei (6n) were essential to the development of southern highbush blueberry cultivars with reduced chilling requirements (Darrow and Camp 1945;Dweikat and Lyrene 1988;Lyrene et al 2003). Intersectional hybrids within Vaccinium have also been reported, but with various levels of vigor and fertility and, in general, have not been successful for introgressing traits of interest between the more distantly related species (Lyrene et al 2003).…”

Since its domestication 200 years ago, breeding of the American cranberry (Vaccinium macrocarpon) has relied on phenotypic selection because applicable resources for molecular improvement strategies such as marker-assisted selection (MAS) remain limited. To enable MAS in cranberry, the first high-density SSR linkage map with 541 markers representing all 12 cranberry chromosomes was constructed for the CNJ02-1 progeny from a cross of elite cultivars, CNJ97-105-4 and NJ98-23. The population was phenotyped for a 3-year period for total yield (TY), mean fruit weight (MFW), and biennial bearing index (BBI), and data were analyzed using mixed models and best linear unbiased predictors (BLUPs). Significant differences between genotypes were observed for all traits. Quantitative trait loci (QTL) analyses using BLUPs identified four MFW QTL on three linkage groups (LGs), three TY QTL on three LGs, and one BBI QTL which colocalized with a TY QTL. Local BLAST of a cranberry nuclear genome assembly identified homologous sequences for the mapped SSRs which were then anchored to 12 pseudo-chromosomes using the linkage map information. Analyses comparing coding regions (CDS) anchored in the cranberry linkage map with grape, kiwifruit, and tomato genomes were Electronic supplementary material The online version of this article (

“…Three blueberry species, that include the highbush blueberry (HB), V. corymbosum L., rabbiteye blueberry (RB), V. ashei Reade (syn. Vaccinium virgatum Ait) and native stands of lowbush blueberry (LB), V. angustifolium Ait, are commercially grown in the United States (Kalt et al, 2001;Lyrene et al, 2003;Hancock et al, 2008;Retamales and Hancock, 2018). Among these species, the HB blueberry is widely grown in the US, accounting for ∼95% of total blueberry production (Kalt et al, 2001;Wang et al, 2019).…”

“…Tetraploid hybrids were achieved by the occurrence of unreduced gametes during pollen formation in the diploid species (Ortiz et al, 1992). Despite interspecific hybridizations, blueberry cultivars are considered autotetraploids with non-preferential bivalent chromosome pairing during meiosis and the absence of chromosome structural differentiation (Qu and Hancock, 1995;Qu et al, 1998;Lyrene et al, 2003). The conventional breeding program employs phenotypic recurrent selection, and the release of a new cultivar can take up to 15 years (Hancock et al, 2008).…”

Insights Into the Genetic Basis of Blueberry Fruit-Related Traits Using Diploid and Polyploid Models in a GWAS Context

Polyploidization is an ancient and recurrent process in plant evolution, impacting the diversification of natural populations and plant breeding strategies. Polyploidization occurs in many important crops; however, its effects on inheritance of many agronomic traits are still poorly understood compared with diploid species. Higher levels of allelic dosage or more complex interactions between alleles could affect the phenotype expression. Hence, the present study aimed to dissect the genetic basis of fruit-related traits in autotetraploid blueberries and identify candidate genes affecting phenotypic variation. We performed a genome-wide association study (GWAS) assuming diploid and tetraploid inheritance, encompassing distinct models of gene action (additive, general, different orders of allelic interaction, and the corresponding diploidized models). A total of 1,575 southern highbush blueberry individuals from a breeding population of 117 full-sib families were genotyped using sequence capture and next-generation sequencing, and evaluated for eight fruit-related traits. For the diploid allele calling, 77,496 SNPs were detected; while 80,591 SNPs were obtained in tetraploid, with a high degree of overlap (95%) between them. A linear mixed model that accounted for population and family structure was used for the GWAS analyses. By modeling tetraploid genotypes, we detected 15 SNPs significantly associated with five fruit-related traits. Alternatively, seven significant SNPs were detected for only two traits using diploid genotypes, with two SNPs overlapping with the tetraploid scenario. Our results showed that the importance of tetraploid models varied by trait and that the use of diploid models has hindered the detection of SNP-trait associations and, consequently, the genetic architecture of some commercially important traits in autotetraploid species. Furthermore, 14 SNPs co-localized with candidate genes, five of which lead to non-synonymous amino acid changes. The potential functional significance of these SNPs is discussed.
